Table 1.

Demographics table. Injury groups did not differ with regards to any demographic variables or baseline executive functioning scores.

	OI (n=119)	Moderate TBI (n=64)	Severe TBI (n=23)	p
Age at Injury (SD)	4.96 (1.00) years	5.06 (1.20) years	5.12 (1.07) years	.80
Gender (% male)	16 (69.57)	37 (57.81)	69 (57.98)	.56

Note: GEC = Behavior Rating Inventory of Executive Function General Executive Composite, OI = Orthopedic Injury, TBI = Traumatic Brain Injury. General linear models were used to examine injury group differences for age at injury, baseline GEC, and zSES. Chi square tests were used to examine group differences for gender and race.

Group comparisons revealed that the OI group had significantly greater SES z-score than the severe TBI group (p = .01). No other group comparisons were significant.
